Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today. Can you list all the medications he has had since the blockage?What ear medication was used?Did his vet thoroughly check his ears with their otoscope before treating with the ear drops?Since your history looks to have been cut off, was there anything else I should know about Chandler (your information ends with "He was...")?
